Mediant 500L MSBR
Parameter Description

[3] Both = Each offer\answer is extended (if not already)
to two media lines - one RTP and the other SRTP.
If two SBC legs (after offer\answer negotiation) use different
security types (i.e., one RTP and the other SRTP), the
device performs RTP-SRTP transcoding. To transcode
between RTP and SRTP, the following prerequisites must be
met:
 At least one supported SDP "crypto" attribute and
parameters.
 EnableMediaSecurity must be set to 1.
If one of the above transcoding prerequisites is not met,
then:
 any value other than “As is” is discarded.
 if the incoming offer is SRTP, force transcoding, coder
transcoding, and DTMF extensions are not applied.
Web: P-Asserted-Identity
CLI: sbc-assert-identity
[IpProfile_SBCAssertIdentity]
Defines the device's handling of the SIP P-Asserted-Identity
header for this SIP entity. This header indicates how the
outgoing SIP message asserts identity.
 [0] As Is = (Default) P-Asserted Identity header is not
affected and the device uses the same P-Asserted-
Identity header (if present) in the incoming message for
the outgoing message.
 [1] Add = Adds a P-Asserted-Identity header. The
header's values are taken from the source URL.
 [2] Remove = Removes the P-Asserted-Identity header.
Notes:
 This parameter affects only the initial INVITE request.
 The corresponding global parameter is
SBCAssertIdentity.
Web: Diversion Mode
CLI: sbc-diversion-mode
[IpProfile_SBCDiversionMode]
Defines the device’s handling of the SIP Diversion header for
this SIP entity.
 [0] As Is = (Default) Diversion header is not handled.
 [1] Add = History-Info header is converted to a Diversion
header.
 [2] Remove = Removes the Diversion header and the
conversion to the History-Info header depends on the
SBCHistoryInfoMode parameter.
For more information on interworking of the History-Info and
Diversion headers, see Interworking SIP Diversion and
History-Info Headers on page 528.
Note: If the Diversion header is used, you can specify the
URI type (e.g., "tel:") to use in the header, using the
SBCDiversionUriType parameter.
Web: History-Info Mode
CLI: sbc-history-info-mode
[IpProfile_SBCHistoryInfoMode]
Defines the device’s handling of the SIP History-Info header
for this SIP entity.
 [0] As Is = (Default) History-Info header is not handled.
 [1] Add = Diversion header is converted to a History-Info
header.
 [2] Remove = History-Info header is removed from the
SIP dialog and the conversion to the Diversion header
depends on the SBCDiversionMode parameter.
